FAQs
For new installations, verify a compatible top-feed wiring arrangement and ensure clearance for a three-pole, three-wire configuration (3NO-3NC). Plan for 2000 A current pathways, 480 V system voltage, and 120 V control power. Provide proper fuse protection and ground fault options as catalog notes indicate. Ensure UL Listed compliance and allow space for the unit's 16 in depth, 24 in width, and 28 in height with a 180 lb weight.
The switch is rated for up to 2000 A and 480 V system voltage, with a charge-before-close mechanism to manage fault events safely. The 3 NO-3 NC configuration supports robust interlocks across three poles, while fusible protection helps limit fault energy. Its ground fault feature enhances protection when control power is transformer-fed, reducing risk to personnel and equipment during switching transients.
Yes. The CB2033T120480KG14 is designed for top-feed wiring and includes fusible protection. It also offers ground fault protection with a control power transformer, which improves safety during fault conditions. The three-pole, 3NO-3NC configuration supports reliable interlock signaling across multiple circuits, making it well-suited for large, safety-critical panels in manufacturing plants.
This unit carries UL Listed certification, indicating compliance with widely recognized safety standards. It is compatible with a range of NEMA enclosures (NEMA 1, 3R, 4, 12) for indoor and outdoor use. While CE and SIL ratings are not listed in the provided data, UL Listing and NEMA compatibility provide substantial regulatory alignment for industrial switchgear applications.
Expect improved reliability due to a rugged three-pole, three-wire configuration and high current rating, reducing unexpected downtime. Ground fault and transformer-assisted control minimize nuisance trips and enhance safety, lowering maintenance costs. The unit’s modular features and optional provisions simplify integration and future upgrades, delivering a favorable total cost of ownership over the life of the switchgear.
